Sentry No-E Double Caps are newly introduced to ensure process fluids and gases cannot escape.
For applications including petrochemical, the new cap has external threads on the existing bottle cap to allow placement of another cap on top of it. This makes certain the sample bottle is completely and safely sealed even though the original cap septum is pierced.
Sentry No-E Double Cap allows you to cap a sample bottle without removing the original cap with pierced septum. This protects operators and their environment while preserving sample integrity.
